If there's one thing that we love as cyclists, it's our bikes; where would we be without them? So keeping our bikes safe when we're away from them is a number one priority. A good quality lock and security system is a priceless investment for any cyclist.
The times when you could use a bike lock are endless, it's not just about the obvious ones, such as leaving your bike at a park or outside a shop, you have to think about bike security as an on-going process. So when you hit that cafe stop on a big ride, and the whole peloton leaves their bikes outside, consider putting a lock on yours. It may seem like there's safety in numbers, but it's better to never take a chance.
Even at home it's best to be safe. Do you keep your bike locked away in a shed or garage? Again, while it is quite safe, these sorts of places are targeted for bike theft, and a good tip is to use a chain lock to tie it to a stationary object such as an attachment on a wall.
Bike locks and chains are the kind of product that will never show their true purpose until the very rare case of a theft, which we all hope will never happen. It is, however, always better to be safe than sorry. If you love your bike, lock it up!
